Catholic Wisdom

"Liberty of spirit has two vices: a spirit of inconstancy and a spirit of constraint. For example: I resolve to make a meditation every morning. If I have a spirit of inconstancy I will defer it till evening at the 88slightest excuse—for the barking of a dog which has disturbed my sleep, for a letter to be written, though it is not at all urgent. On the contrary, if I have a spirit of constraint I will not omit my meditation, even though a sick person is in grave need of my services."

—Saint Francis de Sales, Maxims and Counsels for Every Day, 196.
